Sai Grafio agreed to paint Gerald Weaver and Katherine Brewer's house for $5,650. Weaver and Brewer paid for the paint job in installments but stopped payment on the final $1, 845 check, claiming that Grafio had breached the contract by doing a poor job. The lower court judge found that the only defect in the paint job was a footprint left on the roof that would cost $50 to repair. How much money, if any, and under what legal theory, did the court allow Grafio to recover for the paint job? [See: Weaver v. Grafio, 595 A.2d 983 (DC).]
